The unique properties of lasers create an enormous potential for specific treatment of chronic ear disease. Despite the widespread acceptance and use of the laser, however, a complete understanding of the time- and space-dependent temperature distribution in otic capsule bone immediately after pulsed laser exposure has not been elucidated. Using a liquid nitrogen-cooled mercury-cadmium telluride infrared detector, the temperature distribution in human cadaveric otic capsule bone was determined immediately after pulsed (100 msec) carbon dioxide laser exposure (0.3 to 4.0 W; 200 microm spot diameter). The time- and space-dependent temperature increases and thermal diffusion were determined as a function of the laser power density and were found to vary linearly.
激光的独特特性为慢性耳部疾病的特异性治疗创造了巨大潜力。然而，尽管激光已被广泛接受和使用，但脉冲激光照射后耳囊骨中随时间和空间变化的温度分布尚未得到充分阐明。使用液氮冷却的碲镉汞红外探测器，在脉冲（100毫秒）二氧化碳激光照射（0.3至4.0瓦；光斑直径200微米）后立即测定人尸体耳囊骨中的温度分布。测定了随时间和空间变化的温度升高及热扩散与激光功率密度的函数关系，发现其呈线性变化。
